Abstract
The utility model belongs to an airplane riveting and assembling technology, which relates to a stop dog type one-way spring compressed positioning pin. The stop dog type one-way spring compressed positioning pin comprises an eccentric stop dog [1], a shaft [2], a gasket [3], a spring [4] and a pin body [5], wherein an arc groove is arranged at the head part of the positioning pin; and the eccentric stop dog [1] which can rotate in the arc groove relative to the positioning pin is arranged the arc groove at the head part of the positioning pin through the shaft [2]; the spring [4] is arranged in the middle of the positioning pin; one end of the spring [4] is supported against the pin body [5]; and the other end of the spring [4] is connected with the gasket [3]. The pin body [5] is positioned at the tail end of the positioning pin; and a handle [6] is transversely arranged on the pin body [5]. The stop dog type one-way spring compressed positioning pin can be applied in a closed structure, can be simply operated and has a certain practical application value; the one-way positioning operation of parts can be realized, the one-person operation of positioning the parts in a fixture with a larger area can be realized, and the compressing efficiency of the parts is greatly improved.
Description
Technical field
The utility model belongs to aircraft riveted joint mounting technology, relates to a kind of scotch formula unidirectional spring and compresses alignment pin.
Background technology
In the riveted joint assembly tooling of aircraft product, need a large amount of compressing members, in prepackage, assembling, riveted joint and the parts undercarriage process of part, need often to compress repeatedly or unclamp some compressing members.Adopt at the location of bolt and nut compressing structure because the compressing member of design is most of now, compress or release process in need the rotation very long distance just can work, and for big frock, when locating, part need another people to cooperate the ability complete operation, waste of manpower, it is lower that the location compresses efficient.
Summary of the invention
The purpose of this utility model is: propose a kind ofly to compress the efficient height, scotch formula unidirectional spring simple to operate compresses alignment pin.
The technical solution of the utility model is: a kind of scotch formula unidirectional spring compresses alignment pin, it comprises eccentric scotch, axle, pad, spring, shank, wherein, the head of alignment pin has arc groove, and be provided with the eccentric scotch of doing rotation in can relative positioning pin arc groove by axle, described spring is arranged in the middle of the alignment pin, and the one end heads on shank, the other end and pad join, and described shank is positioned at the alignment pin end.
Be horizontally arranged with handle above the described shank.
The utility model has the advantages that: the utility model scotch formula unidirectional spring compress alignment pin simple to operate, compress the efficient height, can realize unidirectional locating element operation, can be applied in enclosed construction, maybe can realize one man operation than part location in the large tracts of land frock, and spring compression, the location is reliable, special in the assembling process of airplane parts, can Fast Installation, realize that part compresses, and can realize the alignment pin that the one man operation of unidirectional or big surface parts location installs.
Description of drawings
Fig. 1 is the structural representation that the utility model scotch formula unidirectional spring compresses alignment pin one better embodiment;
Fig. 2 is the vertical view of Fig. 1,
Wherein, the eccentric scotch of 1-, 2-axle, 3-pad, 4-spring, 5-shank, 6-handle.
The specific embodiment
Below the utility model is described in further details.
Please consult Fig. 1 and Fig. 2 simultaneously, wherein Fig. 1 is the structural representation that the utility model scotch formula unidirectional spring compresses alignment pin one better embodiment, and Fig. 2 is the vertical view of Fig. 1.Described scotch formula unidirectional spring compresses alignment pin and comprises eccentric scotch 1, axle 2, pad 3, spring 4, shank 5, handle 6.Wherein, eccentric scotch 1 is arranged on by axle 2 in the head arc groove of alignment pin, and eccentric scotch 1 can rotate in the relative positioning pin arc groove.Described spring 4 is arranged in the middle of the alignment pin, and the one end heads on shank 5, and the other end is provided with pad 3.Described shank 5 is positioned at the alignment pin end, is horizontally arranged with handle 6 above.
Using method of the present utility model is: when needing the location to compress part, by handle 6 rotation shanks 5, make under the effect of eccentric scotch 1 circular arc in gravity and shank groove and the same straight line of shank 5 maintenances, shank 5 is sidelong in the tool locating hole from part one.Shank 5 Rotate 180s ° then, eccentric scotch 1 under the effect of gravity with 5 one-tenth plumbness of shank, eccentric scotch 1 blocks the frock hole wall, unclamps alignment pin, spring 4 compresses part naturally, thereby realizes compressing and the locating element effect.When unclamping part, preceding distribution body 5, Rotate 180 °, eccentric scotch 1 under the effect of gravity with shank 5 state that is in line, recall shank 5 then, realize that the taking-up of part is pulled down.Thereby realize compressing fast and unclamping of part.
The utility model scotch formula unidirectional spring compresses alignment pin can realize compressing fast and unclamp part easily, and spring compression, the location is reliable, can realize unidirectional locating element operation, can be applied in enclosed construction, maybe can realize therefore can significantly increasing work efficiency than the one man operation of part location in the large tracts of land frock.
Claims (2)
1. a scotch formula unidirectional spring compresses alignment pin, it is characterized in that: comprise eccentric scotch [1], axle [2], pad [3], spring [4], shank [5], wherein, the head of alignment pin has arc groove, and be provided with the eccentric scotch [1] of doing rotation in can relative positioning pin arc groove by axle [2], described spring [4] is arranged in the middle of the alignment pin, and the one end heads on shank [5], the other end and pad [3] join, and described shank [5] is positioned at the alignment pin end.
2. scotch formula unidirectional spring according to claim 1 compresses alignment pin, it is characterized in that: be horizontally arranged with handle [6] above the described shank [5].
